A novel hierarchical structure , namely, single‐crystalline Si nanowires standing on silica microwires (see Figure), has been prepared by adopting the disproportionation reaction of SiO with metal tin as a liquid‐forming agent. The intense near‐IR photoluminescence displayed by the hierarchical structures suggests possible applications in nanoscale optoelectronic devices.
